摘要：
A process for synthesizing particles of an oxide corresponding to a formula selected from: Li4Ti5O12; Li(4-α)ZβTi5O12; and Li4ZαTi(5-β)O12, said process including the steps of: a) preparing an intimately dispersed ternary mixture of TiOx—LiZY-carbon, wherein x is a number between 1 and 2, z is 1 or 2, Y is a radical chosen from the group consisting of CO3, OH, O and TiO3 or a mixture thereof, and the carbon is a carbon powder selected from the group consisting of natural or artificial graphite, carbon black, Shawinigan black, Ketjen black and cokes; b) heating the dispersion at a temperature of between 400 and 1,000° C.; and c) if appropriate, adding a source of at least one metal Z to the ternary mixture, wherein the operating conditions are chosen in such a way as to yield a conversion of the initial products respectively into Li4Ti5O12, Li(4-α)ZαTi5O12, Li4ZβTi(5-β)O12.
